Absolutely!
First thing you want to do is download "Touch Icon" from the App Store ($0.99 USD). Then, find a good picture of your logo and have it saved in your Photo app. A good size is about 100 x 100 pixels, plus or minus (you may have to experiment).
Open the app and press "URL," then fill in all the fields (name is what you want to have the icon on your springboard named).
You'll see a box with a gray head in it. Press it and you'll be taken to select a photo from your Photos app. Pick your logo and after you finish filling out the URL, press "Create."
The app will open Safari and then prompt you to save to the homescreen. Once you do that, ta da! All done.
The only caveat is that you'll need to keep this app on your iPad, cause removing it will break the link.
Hope that helps. Good luck.

P.S. Oh, and note that you can do this for any bookmark you wish to save/create. I have many bookmarks and this method makes them look as if they are stock icons. Me likes...
